Peptidic spider toxins: a novel paradigm for control of insect pests. Many insects are serious pests of Australian crops, livestock, and pets. Australian farmers spend about $300 million per annum on insecticides and acaricides, while Australian consumers spend more than $100 million annually on insecticides for use around the home and garden, and on pets. Viruses disseminated by insects are also responsible for diseases such as dengue, Japanese encephalitis, and Ross River fever. Unfortunately, ....Peptidic spider toxins: a novel paradigm for control of insect pests. Many insects are serious pests of Australian crops, livestock, and pets.

Viruses disseminated by insects are also responsible for diseases such as dengue, Japanese encephalitis, and Ross River fever. Unfortunately, many of these insect pests have developed resistance to chemical insecticides. The aim of this research program is to develop a new generation of environmentally-friendly natural products and insect-resistant crops that can be used to control insect pests on farms and around the home and garden.Read moreRead less

Safeguarding Australia against invasive arthropod pests. An increasingly serious public health issue for Australia is the emergence of infectious diseases disseminated by arthropods such as ticks and mosquitoes. Arthropod-borne viruses are already the major human pathogens in Australia, and they disproportionately affect Aboriginal communities. The aim of this research is to develop environmentally-sustainable methods for controlling arthropods that destroy crops or disseminate human and animal ....Safeguarding Australia against invasive arthropod pests. An increasingly serious public health issue for Australia is the emergence of infectious diseases disseminated by arthropods such as ticks and mosquitoes. Arthropod-borne viruses are already the major human pathogens in Australia, and they disproportionately affect Aboriginal communities. The aim of this research is to develop environmentally-sustainable methods for controlling arthropods that destroy crops or disseminate human and animal disease. These insecticides will not only provide benefits within Australian territories, but will be useful to our defence forces when operating in overseas locations where arthropod pests are a problem (e.g., malarial regions of Iraq).Read moreRead less
Theoretical and computational approaches to accurately predict the structures of a unique family of circular and knotted proteins. The primary outcome will be a fundamental new knowledge on cyclotide structures and a new protein engineering method to design stabilised proteins. Because cyclotides have significantly higher stabilities than conventional proteins, they have a range of pharmaceutical and agricultural applications. Both fields of use have the potential for very great economic and soc ....Theoretical and computational approaches to accurately predict the structures of a unique family of circular and knotted proteins. The primary outcome will be a fundamental new knowledge on cyclotide structures and a new protein engineering method to design stabilised proteins. Because cyclotides have significantly higher stabilities than conventional proteins, they have a range of pharmaceutical and agricultural applications. Both fields of use have the potential for very great economic and social benefits for Australia. From a pharmaceutical perspective our computing development will greatly facilitate the design of stabilised peptide-based drugs using the cyclotide framework. Such drugs have potential sales of several billion dollars per annum and the royalty returns from successful commercialisation of IP can be substantial.Read moreRead less
Structural studies of plant disease resistance proteins. Plant cells have evolved a gene-for-gene disease resistance mechanism, involving an interaction of a plant-derived receptor with a specific pathogen-derived molecule. Currently, plant breeders are restricted to the resistance genes available in particular crop species or sexually compatible relatives. In the last few years, several plant disease resistance genes have been identified, providing a foundation for studying the molecular basis ....Structural studies of plant disease resistance proteins. Plant cells have evolved a gene-for-gene disease resistance mechanism, involving an interaction of a plant-derived receptor with a specific pathogen-derived molecule. Currently, plant breeders are restricted to the resistance genes available in particular crop species or sexually compatible relatives. In the last few years, several plant disease resistance genes have been identified, providing a foundation for studying the molecular basis of the resistance process. We propose to obtain three-dimensional structural information on representative R proteins and their ligand complexes. This will form the basis for modifying existing resistance genes to confer resistance to new diseases, resulting in large economic benefits.Read moreRead less

Management of crop diseases involves the integrated use of resistant cultivars and the application of chemical pesticides. Many diseases, however, including rust, continue to pose an economically significant threat to agricultural productivity in Australia. The research outlined in this proposal aims to understand the mechanisms, at a molecular and structural level, that enable resistant plants to detect and respond to pathogen attack. The outcomes of this currently unavailable fundamental understanding will enable new, durable and more effective resistance genes to be engineered. Therefore, the work has significant economic and environmental implications for agricultural crop plant productivity in this country.Read moreRead less

Manipulation of apoptosis-related genes to generate novel disease resistances in banana. Bananas are one of Australia's most important fruit crops. However, the industry is continually threatened by numerous diseases including yellow and black Sigatoka, Fusarium wilt and bunchy top. Control of these diseases currently requires either extensive pesticide treatments or complex agronomic procedures, of which most are ineffective, expensive or environmentally damaging. The aim of this project is to ....Manipulation of apoptosis-related genes to generate novel disease resistances in banana. Bananas are one of Australia's most important fruit crops. However, the industry is continually threatened by numerous diseases including yellow and black Sigatoka, Fusarium wilt and bunchy top. Control of these diseases currently requires either extensive pesticide treatments or complex agronomic procedures, of which most are ineffective, expensive or environmentally damaging. The aim of this project is to utilise a novel strategy to generate transgenic bananas with resistance to these diseases. The benefit will be both economic and environmental as implementation should significantly reduce or eliminate pesticide use. Importantly, this strategy can potentially be extrapolated to many other crops.Read moreRead less
